Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Lichtbogenschweißen bestehend aus mindestens zwei Lichtbogenschweißgeräten, insbesondere WIG- oder MIS/MAG-Schweißgeräten, oder mindestens einem Lichtbogenschweißgerät und einer Peripherieeinheit, wie z. B. ein PC oder eine Fernsteuereinheit welche jeweils von einem gemeinsamen elektrischen Versorgungssystem gespeist werden, wobei jedes Lichtbogenschweißgerät ein Leistungsmodul zur Ansteuerung des Schweißprozesses, eine Bedienungseinheit und eine Steuerelektronik aufweist.The invention relates to a device for Arc welding consisting of at least two Arc welding devices, in particular TIG or MIS / MAG welding devices, or at least one Arc welding device and a peripheral unit, such as e.g. B. a PC or a remote control unit which each from a common electrical supply system be fed, each arc welding machine Power module for controlling the welding process, one Control unit and control electronics.
Elektrische Lichtbogenschweißgeräte sind aus dem Stand der Technik bekannt (DE 38 03 447 und DE 38 04 387)Electric arc welding machines are state of the art known in the art (DE 38 03 447 and DE 38 04 387)
Beim Aufbau eines Systems bestehend aus mehreren Lichtbogenschweißgeräten, die beispielsweise mit einer Gruppe von Schweißrobotern arbeiten, erfolgt die Leistungsversorgung der Lichtbogenschweißgeräte in der Regel über ein gemeinsames elektrisches Versorgungsnetz. Wenn ein Austausch von Prozeßdaten oder von Steuerinformationen von einem Lichtbogenschweißgerät zum anderen erforderlich ist, erfolgt dies in der Praxis dadurch, daß hierzu separate Leitungen zwischen den zu verbindenden Lichtbogenschweißgeräten errichtet werden, über die eine Kopplung erfolgt. Ein Beispiel für eine solche Kopplung sind sogenannte Can-Bus-Steuerungssysteme, die aus der Praxis bekannt sind. Ein Nachteil solcher Systeme besteht darin, daß separate Steuerkabel zwischen den einzelnen Lichtbogenschweißgeräten erforderlich sind. Aus der EP 0 575 082 ist ein Lichtbogenschweißgerät bekannt, bei welchem der Austausch von Prozeßdaten zwischen der Schweißelektrode und dem Schweißgerät über die elektrische Versorgungsleitung zum Schweißprozeß erfolgt.When building a system consisting of several Arc welding equipment, for example with a Group of welding robots work, the Power supply of the arc welding devices in the Usually via a common electrical supply network. If an exchange of process data or of Control information from an arc welder to other is required, this is done in practice in that separate lines between the connecting arc welding devices are set up, via which a coupling takes place. An example of a such coupling are so-called can-bus control systems, that are known from practice. On The disadvantage of such systems is that separate Control cables between each Arc welding equipment is required. An arc welding device is known from EP 0 575 082 known in which the exchange of process data between the welding electrode and the welding machine the electrical supply line to the welding process he follows.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art dahingehend weiterzuentwickeln, daß separate Steuerkabel für die Datenübertragung zwischen den Lichtbogenschweißgeräten bzw. einem Lichtbogenschweißgerät und einer Peripherieeinheit entfallen können.The invention has for its object a Device of the type mentioned in this regard further develop that separate control cable for the Data transmission between the arc welding devices or an arc welder and one Peripheral unit can be omitted.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß jedes der mindestens zwei Lichtbogenschweißgeräte bzw. das mindestens eine Lichtbogenschweißgerät und die mindestens eine Peripherieeinheit ein Kopplungsmittel aufweisen zum Ein- bzw. Auskoppeln von Prozeßdaten und/oder von Steuerinformationen in das elektrische Versorgungssystem.This object is achieved in that each of the at least two arc welding devices or the at least one arc welding device and the at least one peripheral unit a coupling means have for coupling in and out process data and / or control information in the electrical Supply system.
Die Erfindung zeichnet sich dadurch aus, daß zwischen
verschiedenen Schweißmaschinen bzw. Peripherieeinheiten
Informationen in Form von Daten ausgetauscht werden
können, ohne daß zusätzliche Verbindungskabel
erforderlich sind. Das ohnehin vorhandene
Versorgungssystem dient neben seiner ursprünglichen
Aufgabe der zur Verfügungstellung der entsprechenden
Leistung auch als Träger für ein Datennetzwerk, in dem
der vorhandenen Netzspannung die entsprechenden
Prozeßdaten und/oder Steuerinformationen nach bekannten
Verfahren aufmoduliert bzw. von diesen demoduliert
werden. Damit ist es möglich, schweißrelevante Daten, wie
z.B. Schweißstrom, Schweißspannung oder
Drahtvorschubgeschwindigkeit zwischen den einzelnen
Lichtbogenschweißgeräten bzw. Peripheriegeräten ohne
zusätzliche Kabel zu übertragen.
Das so gebildete Datennetzwerk zwischen den einzelnen
Schweißgeräten und den Peripheriegeräten ermöglicht, daß
der Datenaustausch auch bei großer räumlicher Entfernung
erfolgen kann. Durch den Aufbau eines solchen Netzwerkes
können die Daten bei einem beispielsweise als PC
gestalteten Peripheriegerät von diesem überwacht oder
archiviert werden. Eine denkbare Variante sieht auch vor,
daß über eine entsprechende graphische Darstellung die
Schweißprozeßdaten dem Anwender auf einer Anzeige
sichtbar gemacht werden können.The invention is characterized in that information in the form of data can be exchanged between different welding machines or peripheral units without the need for additional connecting cables. In addition to its original task of providing the corresponding power, the supply system, which is present anyway, also serves as a carrier for a data network in which the corresponding process data and / or control information is modulated onto or demodulated by the known mains voltage using known methods. This makes it possible to transfer welding-relevant data, such as welding current, welding voltage or wire feed speed, between the individual arc welding devices or peripheral devices without additional cables.
The data network formed in this way between the individual welding devices and the peripheral devices enables the data exchange to take place even over great spatial distances. By setting up such a network, the data can be monitored or archived by a peripheral device designed, for example, as a PC. A conceivable variant also provides that the welding process data can be made visible to the user on a display by means of a corresponding graphical representation.
Wenn in einer weiteren bevorzugten Ausführungsform vorgesehen ist, daß das Kopplungsmittel ein Hochfrequenzmodem ist, welches einen Hochfrequenzsender und einen Hochfrequenzempfänger jeweils aufweist, derart, daß den Prozeßdaten entsprechende Signale auf die speisende Netzspannung aufmodulierbar bzw. von dieser demodulierbar ist, ist es möglich, daß über die Hard- und Software-Adressierung Schweißdaten von einem PC von mehreren Schweißenergiequellen oder Periphiergeräten empfangen werden können.If in another preferred embodiment it is provided that the coupling means Radio frequency modem is what a radio frequency transmitter and each has a radio frequency receiver, such that the process data corresponding signals to the supplying mains voltage can be modulated or from this is demodulatable, it is possible that the hardware and Software addressing welding data from a PC by several welding energy sources or peripheral devices can be received.
Andererseits können auch die von einem Anwender erstellten Schweißprozeßparameter vom PC aus zu mehreren Schweißquellen oder Peripheriegeräten gesendet werden. Damit kann beispielsweise die Schweißaufsicht einer Werkhalle mit nur einem PC sämtliche Schweißstromquellen dieser Halle programmieren, ohne mehr als die Netzleitung zu benötigen. On the other hand, that of a user created welding process parameters from the PC to several Welding sources or peripheral devices are sent. For example, the welding supervisor can Workshop with only one PC all welding power sources program this hall without more than the power cord to need.
Von einer Mastersteuerung, z.B. der Steuerelektronik
einer Masterstromquelle oder von einer Fernsteuereinheit,
können über die Netzleitung Befehle und Daten zwischen
verschiedenen Schweißstromquellen und/oder
Peripheriegeräten ausgetauscht werden.
Weitere bevorzugte Ausführungsformen gehen aus den
weiteren Unteransprüchen hervor.Commands and data can be exchanged between different welding current sources and / or peripheral devices from a master control, for example the control electronics of a master current source or from a remote control unit.
Further preferred embodiments emerge from the further subclaims.

16 gesteuert ist. Dem Mikroprozessor 13 ist ein Hard- und
Software-Adressdekoder 15 zugeordnet, über den dem
Koppelmodul 5 eine bestimmte Hard- und Software-Adresse
zugewiesen wird.The connection between the

die Netzspannungsleitung 6 übertragen.The data output by the

Durch die beschriebene Einheit wird ein Datennetzwerk zwischen den verschiedenen Schweißgeräten und den Peripheriegeräten auf einfache Art und Weise aufgebaut. Der Datenaustausch zwischen den Schweißgeräten und/oder Peripheriegeräten erfolgt dabei ohne das Erfordernis einer zusätzlichen Leitung ausschließlich über die bestehende Netzspannungsversorgungsleitung.The described unit creates a data network between the different welding machines and the Peripherals built in a simple way. The data exchange between the welding machines and / or Peripherals are done without the requirement an additional line exclusively via the existing mains voltage supply line.
Eine erste praktische Anwendung der Erfindung besteht
darin, daß beim gleichzeitigen WIG-Schweißen mit
Wechselstrom zwei Schweißstromquellen 1 über zwei
Schweißbrenner 7 auf ein gemeinsames Werkstück arbeiten.
Wenn die Schweißströme hinsichtlich ihrer
Wechselstromfrequenz, Polarität, Wechselstrombalance und
Schweißstromhöhe nicht miteinander synchronisiert werden,
beeinflussen sich die beiden Lichtbögen der
Schweißstromquellen ungünstig. Dies kann vermieden
werden, wenn gemäß der Erfindung ein Datenaustausch
zwischen den beiden Schweißstromquellen 1 erfolgt, wobei
dies ohne zusätzliche Datenübertragungskabel und
unabhängig von der räumlichen Entfernung der beiden
Schweißstromquellen zueinander geschehen kann.There is a first practical application of the invention
in that with simultaneous TIG welding with
AC two

Stromquellen 1 über zwei Schweißdrähte in einem
Schweißbrenner auf ein Werkstück arbeiten (MIG-MAG-Doppeldrahtschweißen).

Stromquellen erfindungsgemäß über die gemeinsame
Netzstromversorgung miteinander synchronisiert werden.
Besondere Bedeutung ist der übergeordneten Steuerung
durch eine Periphiereinheit, beispielsweise einen PC
zuzumessen:A second use case is that two

Schnittstelle mit einem Koppelmodul mit der
Netzspannungsversorgung 6 verbundenen PC 8 ist es
möglich, schweißrelevante Daten, wie z.B. Schweißstrom,
Schweißspannung und Drahtvorschubgeschwindigkeit von der
Stromquelle 1 auch über weite Entfernungen an den PC 8 zu
übertragen.By exchanging data between the serial
Interface with a coupling module with the
Dadurch, daß jeder Einheit über den Adressendekoder 15
eine separate Hard- bzw. Software-Adresse zugewiesen
wird, läßt sich ein System aufbauen, bei welchem Befehle
und Prozeßdaten zwischen verschiedenen
Schweißstromquellen 1 und/oder Peripherie wahlweise
ausgetauscht werden können, beispielsweise in Form einer
Mastersteuerung.The fact that each unit via the address decoder 15th
